Releasing wind umbrella

ABSTRACT

An umbrella for releasing wind includes a few dozens of holes on the top of cloth and a few dozens of sleeve-shaped channels affixed over each hole. The diameter sizes of the holes are different. The sleeve-shaped wind-release channel is a hollow cylinder. It has a bigger and a small end. The big end of the sleeve is directly attached to the hole on the top of surface. The small end of the sleeve has curved finish. When the wind blows into the channel from inside of umbrella, the sleeve-shaped channel becomes erect so the wind is discharged through the hole, the channel and the small side of the sleeve.

BACKGROUND OF THE INVENTION

[0001] A conventional umbrella is comprised by an umbrella axis,multiple supporting ribs and the cloth cover. The design of conventionalumbrella avoids or eliminates the sufferings under the rain and snowweather, to guard people from sunlight, rain fall or snow fall.

[0002] However, the structure of conventional umbrella has somedisadvantages such as when the wind blows from inside of the umbrella,there is no sufficient way to allow the escape of the wind. A potentialflip-over, blown down or broken of the umbrella still exist. It isinconvenient to use. The structure of the releasing wind umbrellaimproves the condition of conventional umbrella.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0007] As FIG. 1 shown, this new invention is an umbrella withsleeve-shaped channels for releasing wind. The umbrella can effectivelydischarge the wind blown into the umbrella. There are a few dozens ofsleeve-shaped wind-release channels affix to the umbrella surface asshown by (4) and (5). (1) and (2) are the enlarged view of (4) and (5)respectively. (2) is the bigger end of the sleeve, directly attached toholes on the umbrella surface. (1) is the small end of the sleeve, lyingflat on the umbrella surface when the umbrella is fully open and thereis no wind. The sleeve-shaped wind-release channel is a hollow cylinder.When the wind blows into the channel from inside of umbrella, as shownby (10) and (11), the sleeve-shaped channel becomes erect so the wind isdischarged through the hole on the umbrella surface, sleeve-shapedchannel and the small side of the sleeve. As shown by (12), (13) and(14), the small side of the sleeve has curved finish (7) and (8). Suchdesign is to prevent rainwater from leaking into the wind-releasechannel while releasing wind all the way from (6) through (9). Therecould be a few dozens of the wind-release holes on one umbrella surface,distributed around the surface in circles as shown by (17), (18) and(19). Sleeve-shaped channel has two ends, big end and small end. The bigend (16) is seamlessly affixed to the holes on the umbrella surface. Theconnection method could either be a glue or sewing. The small end (15)usually lies flat on the umbrella surface. The size ratio between bigand small end of the wind-release channel should not be too large. Curvefinish end (23) should have appropriate angle, and correspondingthickness. This design is a unique invention with great advantage. Ihereby apply to your office for a patent grant.

What is claimed is:
 1. An umbrella structure for releasing windcomprising: A few dozens of holes on the cloth of umbrella surface; Afew dozens of sleeve-shaped wind-release channels; The sleeve-shapedchannel has two ends, big end and small end.
 2. The umbrella structureas claimed in claim 1, wherein the hole and sleeve-shaped channel areconnected; both are even distributed around the handle on the surface ofthe umbrella. The diameter of the holes has different sizes according tothe wind power. The small side of the sleeve has curved finish. Suchdesign is to prevent the rain water from leaking into the wind-releasechannel while releasing wind all the way from the hole through thesleeve to the small end of the sleeve. The big end of the sleeve isseamlessly affixed to the hole on the umbrella surface. The connectionmethod could either be a glue or sewing. The ratio size between big andsmall end of the wind-release channel should not be too large, it shouldtake the size as the sleeve can lie flat on the umbrella surface.
